Vernier least count
$LC = 1 MSD - 1 VSD$
Vernier LC (standard)
$LC = \frac{1 MSD}{N}$
Screw gauge least count
$LC = \frac{pitch}{no. of divisions}$
Pitch of a screw
$pitch = \frac{distance moved}{no. of rotations}$
Reading (vernier)
$reading = MSR + VSR \times LC$
Zero error correction
$true = observed - zero error$
Meter bridge unknown resistance
$X = \frac{( 100 - l )}{l} R$
Percentage error
$\frac{Δ a}{a} \times 100$
Simple pendulum g
$g = \frac{4 π ^{2} L}{T ^{2}}$
Focal length (u-v method)
$\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$
Ohm's law verification
$V = I R$
Sonometer frequency
$f = \frac{1}{2 L} \frac{T}{μ}$
Specific heat (calorimetry)
$m_{1} s_{1} Δ T_{1} = m_{2} s_{2} Δ T_{2}$
Young's modulus (Searle)
$Y = \frac{F L}{A Δ L}$
Resistance from color code
$value = A B \times 1 0^{C} Ω$
Refractive index (real/apparent depth)
$μ = \frac{real depth}{apparent depth}$
